Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) and leakage currents 3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Page 72
(Check it in the data of the corresponding breaker.) As an earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge suppression. Selecting the rated sensitivity current for the earth leakage circuit breaker When using an earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency.
Electro-magnetic interference (EMI) and leakage currents NOTE • Install the earth leakage circuit breaker (ELB) on the input side of the inverter. • In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
Page 74
Electro-magnetic interference (EMI) and leakage currents Noise propagation Countermeasure path When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are near the inverter or when the signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.

Electro-magnetic interference (EMI) and leakage currents • Switching ON/OFF the filter (1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is OFF, wait for at least 10 minutes after the power supply has been switched OFF, and check that there is no residual voltage using a tester or the like.
Power supply harmonics Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Power supply harmonics 3.2.2 Harmonic suppression guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products"...

Power-OFF and magnetic contactor (MC) Power-OFF and magnetic contactor (MC) Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes: (Refer to page 14 for selection.) • To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).
Countermeasures against deterioration of the 400 V class motor insulation Countermeasures against deterioration of the 400 V class motor insulation In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially in a 400 V class motor, the surge voltage may deteriorate the insulation.

Checklist before starting operation Refer Check Checkpoint Countermeasure page user If the machine must not be restarted when power is restored after a power failure, provide an MC in the inverter's input side and also make up a A countermeasure is provided for sequence which will not switch ON the start signal.
Although Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
Page 86
Failsafe system which uses the inverter (d) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal The output current detection signal (Y12 signal) is output when the inverter operates and currents flows into the motor. Check if Y12 signal is being output while inputting a start signal to the inverter.

Inspection item 5.1.4 Checking the inverter and converter modules Preparation • Disconnect the external power supply cables (R/L1, S/L2, T/L3) and motor cables (U, V, W). • Prepare a tester. (For the resistance measurement, use the 100 Ω range.) Checking method Change the polarity of the tester alternately at the inverter terminals R/L1, S/L2, T/L3, U, V, W, P/+, and N/- and check the electric continuity.
The estimated lifespan is only a guide. To maintain the waterproof and dustproof performances of the inverter, daily and periodic inspections are recommended. NOTE • For parts replacement, contact the nearest Mitsubishi FA center. Displaying the life of the inverter parts The inverter diagnoses the main circuit capacitor, control circuit capacitor, cooling fan, internal fan, and inrush current limit circuit by itself and estimates their lives.

Measurement of main circuit voltages, currents, and powers 5.2.1 Measurement of powers Use digital power meters (for inverter) for the both of inverter input and output side. Alternatively, measure using electrodynamic type single-phase wattmeters for the both of inverter input and output side in two-wattmeter or three- wattmeter method.
Measurement of main circuit voltages, currents, and powers 5.2.3 Measurement of currents Use moving-iron type meters on both the input and output sides of the inverter. However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of the meter will increase and the meter may burn out.
Measurement of main circuit voltages, currents, and powers 5.2.7 Measurement of inverter output frequency In the initial setting of the FM-type inverter, a pulse train proportional to the output frequency is output across the pulse train output terminals FM and SD of the inverter. This pulse train output can be counted by a frequency counter, or a meter (moving-coil type voltmeter) can be used to read the mean value of the pulse train output voltage.
